奧林匹亞科斯

Olympiacos Men's Volleyball (Greek: Ολυμπιακός, [olimbiaˈkos]), commonly referred to as Olympiacos, Olympiacos Piraeus or with its full name as Olympiacos SFP, is the men's professional volleyball department of the major Greek multi-sport club, Olympiacos SFP, based in Piraeus, Attica. The department was founded in 1926 and their home ground is the Melina Merkouri Indoor Hall in Agios Ioannis Rentis, Piraeus.

Olympiacos is the most successful club in Greek volleyball history, having won 31 Greek Volley League titles, 17 Cups, 6 League Cups, all national records, and 2 Super Cups. They are the only volleyball club in Greece to have won a European title, having actually won 3 European titles, 2 CEV Cups in 1996 and 2005 and 1 CEV Challenge Cup in 2023. Olympiacos is a traditional powerhouse in European volleyball, having played in 8 European finals in all three main CEV competitions: 2 times runners-up in the CEV Champions League in 1992 and 2002 (with 7 CEV Champions League final four participations), 2 times winners (1996, 2005) and 2 times runners-up (1997, 1998) in the CEV Cup, one-time winners (2023) and one time runners-up (2018) in the CEV Challenge Cup.

Domestically, Olympiacos holds the record for the most consecutive championships won, with eight in a row (1987–1994), and for winning seven championships undefeated (1968, 1974, 1979, 1981, 1988, 1991, 2018). Internationally, their most successful period was between 1992 and 2005, when they came to be included amongst the top volleyball powers in Europe. During this period, apart from their two European trophies, they progressed to eleven final fours in total, seven of them consecutive between 1992 and 1998 (the first four in the CEV Champions League and the next three in the CEV Cup Winners' Cup); they also won a fourth place in the CEV Super Cup and a third in the FIVB Volleyball Men's Club World Championship. Olympiacos came to European prominence again by playing in the 2017–18 CEV Challenge Cup final; at the same time, the women's department won their respective 2017–18 CEV Women's Challenge Cup. In this way, Olympiacos became the first volleyball club that had men and women playing simultaneously in European finals, and one of the very few to have won European trophies in both departments. In 2023, they won the CEV Challenge Cup, beating rivals Panathinaikos in the semi-finals and Maccabi Tel Aviv in the final.

Given the fact that Olympiacos is the most popular sports club in Greece, the men's volleyball department also receives great home support. Apart from some top Greek players such as Marios Giourdas, Giorgos Ntrakovits, Sakis Moustakidis, Vasilis Kournetas, Antonis Tsakiropoulos, Kostas Christofidelis, Mitar Tzourits, Olympiacos has also attracted over the years some foreign world-class players including Ivan Miljković, Lorenzo Bernardi, Jeff Stork, Marcos Milinkovic, Bengt Gustafsson, Raimonds Vilde, Vasa Mijić, Tom Hoff, Goran Vujević, Henk-Jan Held, Osvaldo Hernández, Fabian Drzyzga and Dragan Travica.
